SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 505,286, datedSeptember 19, 1893.

Application filed May 22, 1893. Serial No. 475,099. (No model.) i

To all whom it may concern:

Be it known that I, Fennnnrox W. CAR- NELL, of New Haven, in the countyof New Haven and State of Connecticut, have invented a new Improvementin Snap-Hooks; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, 1n

Fig. 1, a view in side elevation of one form which a hook constructed inaccordance with my invention may assume; Fig. 2, a plan view thereof;Fig. 3, a View thereof in vertical longitudinal section; Fig. 4, a viewof the hook in transverse section on the line w-ac of Fig. 1; Fig. 5, adetached view in side elevation of the wire as bent into form; Fig. 6, adetached view of the blank from which the case is formed; Fig. 7, adetached view of the bolt; Fig. 8, a view in transverse section showinga modified form of case.

My invention relates to an improvement in snap-hooks, the object beingto produce a simple, strong, durable and effective article at a low costfor manufacture.

With these ends in view, my invention consists in a snap-hook havingcertain details of construction and combinations of parts as will behereinafter described and pointed out in the claims.

In carrying out my invention, I take a heavy piece of Wire of suitablelength, and bend and shape it to form an eye A,- a body-portion B, and ahook-proper C. I do not limit myself to bending the wire in theparticular way shown, as it may be shaped as requirement or fancy maydictate.

To the body-portion B, of the hookI apply a case, which, as hereinshown, consists of a piece or strap D, of sheet-metal, which is bent andapplied to the body-portion of the hook in theform of the letter S, asshown by Fig. 4c of the drawings, one loop of the strap when thus bent,embracing the body-portion of the hook, and the other loop embracing anextension A, from the base of the eye A, thereof, the said extensionbeing in fact one end of the wire. If the case is appliedin this way,

suflicient space must be left between the body portion B of the hook andthe extension A, thereof, to permit the strap of sheet-metal to bepassed between the same. The case thus formed receives the bolt E, andthe coiled spring F, which is interposed between the extension A, beforementioned, and the inner end of the bolt, which is arranged in alignmentwith the end of the hook-proper C. The said bolt is provided with abutton or fingerpiece E, the shank e, of which plays back and forth in aslot d,formed to receive it in the case D. The extension A, beforementioned, forms, as it will be observed, not only an abutment for'thespring, but also a lock or key for preventing the case from turning onthe body-portion B, of the hook. The extension A, might in fact beregarded as a part of the body-portion, though for conven ence ofdescription it has not been so mentioned herein. I do not limit myselfto constructing or applying the case as described, but when constructedand applied as shown, it is strong and effective, and gives thecompleted article an attractive appearance. If desired, it m ght consistof a strap applied as shown in Fig. 8 of the drawings, in which G,represents the case, H, the body-portion of the hook, and I, theextension of the eye thereof.

By forming the eye,body-portion and hookproper from a single piece ofwire, I am enabled to produce a snap-hook at a very low cost formanufacture, which shall possess exceptional strength, not only onaccount of the inherent strength of the wire, but because it suffers nodeterioration of strength during manufacture, While on the otherhandcast snap-hooks, as generally made, have their hooks cast out of placefor convenience 1n drawing, and are then twisted and brought intoposition.

In View of the suggestions made, I would have it understood that I donot limit myself to the exact construction herein shown and described,but hold myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of my invention. I am aware,however, that a snap-hook having its body-portion and hook formed from asingle piece of wire, and provided with a sheet metal case or barrelcontaining a bolt, is old,

and I do nottherefore broadly claim that construction.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A snap-hook having an eye, body-portlon, hook-proper, and anextension from the base of the eye, all formed from a single pieae ofwire, a case applied to the said body-portion and extension, and a boltlocated in the case, the said extension constituting a lock or key toprevent the case from turning on the body-portion of the hook,substantially as described.

2. A snap-hook having an eye, body-portlon, hook-proper, and anextension from the base of the eye, all formed from a single piece ofwire, a sheet-metal case applied to the said body-portion and extension,a bolt located in 20 the case, and a spring interposed between theextension and the bolt, the said extension constituting a lock or key toprevent the case from turning on the bod y-portion of the hook, and alsoconstituting an abutment for the spring, substantially as described.

3. A snap-hook having its eye, body-portion and hook proper formed froma single piece of wire, a sheet-metal case applied to the saidbody-portion in the form of a letter S and adapted to embrace the saidbody-portion, and an extension from the base of the eye, and a boltlocated in the said case, substantially as described.

In testimony whereof I have signed this Specification in the presence oftwo subscribing witnesses.

FREDERICK W. CARNELL.
